All I can remember is a scene

This is little to nothing to work with but I can’t figure it out and it’s driving me insane. In the scene there is a guy and a girl standing a few feet apart and the guy licks his finger and sticks it in her ear and she kinda cringes when he does it but she keeps a smile on her face the entire time and doesn’t react much at all also I think the guy says something like “ok now that’s just freaky” but I could be wrong.

Got something to say?
